Description

また、カスケード熱交換器４３Ａ、４３Ｂは、低段側ガスクーラ２６を出た冷媒を過冷却するので、低段側ガスクーラ２６、２６で冷却された低段側冷媒回路６Ａ、６Ｂの二酸化炭素冷媒をカスケード熱交換器４３Ａ、４３Ｂにて更に過冷却することになり、更なる冷却能力を改善を図ることができるようになる。 Further, since the cascade heat exchangers 43A and 43B supercool the refrigerant that has exited the low stage side gas cooler 26 , the carbon dioxide refrigerant of the low stage side refrigerant circuits 6A and 6B cooled by the low stage side gas coolers 26 and 26 is used. Further cooling is performed by the cascade heat exchangers 43A and 43B, and further cooling capacity can be improved.
